This manga just drags on and on

This manga could’ve ended in like 100-120 chapters if most of these characters weren’t such idiots(╯°Д °)╯╧╧ like seriously the only likable girl is Sumi. Ruka is too young and naive, Mami is a manipulative bitch and Chizuru is just so damn dense. I’ve never seen a more idiotic male manga protagonist either. At this point the manga won’t end for another 200 damn chapters ┑(￣Д ￣)┍
